The invention concerns the use in a stabilising composition for halogenated polymers, of at least a silylated compounds of formula: (R?1¿)¿4-x?-Si[O-C(R?2¿)=CH¿2?-C(=O)(R?3¿)]¿x?, wherein R?1¿, identical or different, represent an aliphatic or aromatic radical; said radicals being selected such that the silylated compound has a boiling point higher than at least 30 ·C relative to the working temperature of said polymer; R?3¿ represents an aliphatic radical R or a radical -OR?1¿; R?2¿, R and R?1¿, identical or different, represent an aliphatic radical, linear or not, comprising 1 to 10 carbon atoms, or an aromatic radical, preferably comprising 6 carbon atoms, optionally substituted by at least an aliphatic radical comprising 1 to 10 carbon atoms; x is equal to 1 or 2.

La présente invention a pour objet l'utilisation dans une composition stabilisante pour polymères halogénés, d'au moins un composé silylé de formule suivante :(R1)4-x-Si [O-C (R2)=CH2-C(=O)(R3)]x Formule dans laquelle R1, identiques ou non, représentent un radical aliphatique ou aromatique ; lesdits radicaux étant choisis de telle sorte que le composé silylé présente une température d'ébullition supérieure d'au moins 30~C par rapport à la température de mise en forme dudit polymère ;R3 représente un radical aliphatique R ou un radical -OR' ; R2, R et R', identiques ou non, représentent un radical aliphatique, linéaire ou non, comprenant 1 à 10 atomes de carbone, ou un radical aromatique, de préférence comprenant 6 atomes de carbone, éventuellement substitué par au moins un radical aliphatique comprenant 1 à 10 atomes de carbone ; x vaut 1 ou 2.
